Fewer algorithmic complexity surprises, nicer errors, mapcarX(), maplist()
src/ChangeLog addition:
2010-09-01 Aidan Kehoe <kehoea@parhasard.net>
* fns.c (list_merge, list_array_merge_into_list)
(list_array_merge_into_array):
Avoid algorithmic complexity surprises when checking for
circularity in these functions.
(Freduce): Fix some formatting, in passing.
(mapcarX): Drop the SOME_OR_EVERY argument to this function;
instead, take CALLER, a symbol reflecting the Lisp-visible
function that called mapcarX(). Use CALLER with
mapping_interaction_error() when sequences are modified
illegally. Don't cons with #'some, #'every, not even a little.
(Fmapconcat, FmapcarX, Fmapvector, Fmapcan, Fmapc, Fmap)
(Fmap_into, Fsome, Fevery): Call mapcarX() with its new
arguments.
(Fmapcan): Don't unnecessarily complicate the nconc call.
(maplist): Take CALLER, a symbol reflecting the Lisp-visible
function that called maplist(), rather than having separate
arguments to indicate mapl vs. mapcon.
Avoid algorithmic complexity surprises when checking for
circularity. In #'mapcon, check a given stretch of
result for well-formedness once, which was not previously the
case, despite what the comments said.
(Fmaplist, Fmapl, Fmapcon):
Call maplist() with its new arguments.

The files of Emacs are written so as to have no initialized data that can ever need to be altered except at the first startup. This is so that those words can be dumped as sharable text. It is not possible to exercise such control over library files. So it is necessary to refrain from making their data areas shared. Therefore, this file is loaded following all the files of Emacs but before library files. As a result, the symbol my_edata indicates the point in data space between data coming from Emacs and data coming from libraries. */ #include <config.h> char my_edata[] = "End of Emacs initialized data"; /* Ensure there is enough slack in the .bss to pad with. */ #ifdef HEAP_IN_DATA #define BSS_PADDING 0x1000 #else #define BSS_PADDING 1 #endif char my_ebss [BSS_PADDING];
